Super-paramagnetic iron oxide (SPIO) labeling analysis. (A) Phenotypic analysis after SPIO labeling. Prussian blue staining in tumor sections obtained from animals scanned by MRI at day 24. (B) Images show intense blue clusters in tumor sections. (B1) SPIO-labeled bone marrow-derived human mesenchymal stem cells (BM-hMSCs); (B2) SPIO-labeled human adipose-derived stem cell (hASCs); (B3) SPIO-labeled human epithelial endometrium-derived stem cell (hEESCs); (B4) SPIO-labeled human stromal endometrium-derived stem cells (hESSCs); (B5) SPIO-labeled human amniotic membrane mesenchymal stem cells (hAMCs; (B6) control cells. Original magnification: (B1-B5) ×20; (B6) ×10. (C) number of Prussian blue-stained positive cells per high-power field (HPF) in tumor sections.
